The umbrella and the sky are well exposed, however, I don't find the connection between the image and the title (there is nothing that tells me in the image that the weather was hot or whatever, except the umbrella being exposed to the sun), and the trail in the sky doesn't contribute.
I guess there is a table under the umbrella (or seats?) so maybe take a jug of lemonade with lemons, mint and ice in it and shoot it to add some more interesting details to the image.
I guess I'm going rant by now, but just suggesting some ideas.

Thanks for the feedback and ideas, i'll try that if i get a chance. I only titled the it 'Hot Weather' because the umbrella tells me there's somewhere to cool down in the shade from the hot sun. I think i should change the title....
